### Package build options
The supported build options for a source package can be shown with `xbps-src show-options`:
$ ./xbps-src show-options foo
Build options can be enabled with the `-o` flag of `xbps-src`:
$ ./xbps-src -o option,option1 foo
Build options can be disabled by prefixing them with `~`:
$ ./xbps-src -o ~option,~option1 foo
Both ways can be used together to enable and/or disable multiple options
at the same time with `xbps-src`:
$ ./xbps-src -o option,~option1,~option2 foo
The build options can also be shown for binary packages via `xbps-query(8)`:
$ xbps-query -R --property=build-options foo
Permanent global package build options can be set via `XBPS_PKG_OPTIONS` variable in the
`etc/conf` configuration file. Per package build options can be set via
`XBPS_PKG_OPTIONS_<pkgname>`.
> NOTE: if `pkgname` contains `dashes`, those should be replaced by `underscores`
i.e `XBPS_PKG_OPTIONS_xorg_server=opt`.
The list of supported package build options and its description is defined in the
`common/options.description` file or in the `template` file.
